Sergey Sharybin (sergey) added a comment to T50522: OpenCL kernel build fails on Linux with Mesa drivers (RX 480).

The back trace in report indicates crash somewhere inside of Mesa/LLVM. We can not fix that or patch from Blender side, the driver itself is to be brought to a state when it can handle complexity of Cycles kernels.

Markus (blenderuser2) added a comment to T50522: OpenCL kernel build fails on Linux with Mesa drivers (RX 480).

I understand this is not a Blender issue, however six months after the various bugs were filed, Blender 2.79 still crashes on compilation under Ubuntu 17.10 Beta 2 with LLVM 5.0 and Mesa 17.2.2, even though it appears to me that all reported bugs were fixed.

It would have been nice to solve this, but for the next release we will require macOS 10.9 minimum. Apple themselves stopped supporting macOS 10.7 3 years ago.

Ulysse Martin (youle) added a comment to D2734: Buffer Protocol for bgl.Buffer.

Hello, I tested with most of my files using bgl and it worked fine for me. I had only 1 file to test with bge.texture and bgl however. But this sounds ok to me.

I undo some of my changes. It may be best to leave the original Buffer structure untouched.

Caden Mitchell (CadenMitchell) added a comment to T51576: Blender crash when change to edit mode with Intel GPU.

I get the EXCEPTION_ACCESS_VIOLATION error every time on Linux with HD 3000 GPU on laptop. This crashes my computer completely (not just Blender) and I have to power off with power button. This is a problem on Manjaro KDE, Kubuntu, Ubuntu Gnome, and Zorin OS 12. Most of the time this only happens with a high poly object and being close to it with perspective. If using orthographic view it never crashes for me. This may be the best solution for Intel users at least for now.

It really makes sense bgl.Buffer to have a Buffer Protocol.
I made some changes to the code.

Sorry for the late response.
It is related to setting on Windows using Advanced System Settings > Environment variables setting so the command line executable can be executed easily.

Same issue here with intel HD 4600 on windows 10, after hitting tab, blender crash. Latest drivers from intel installed 20.19.15.4703. On linux also crash, not after TAB but crash. Tried several blender 2.8 builds, they all crash, including latest as of this writing.

wilson christian (wilboy) added a comment to T52691: Can't able to start blender.

Concerning the warning in the console - it is harmless and it comes from the Audaspace library.
To make it not show anymore go to File > User Preferences > System. Find the Sound label on the left and under it the` Sample Rate` drop down menu. In your case, pick 192 kHz and press the Save User Settings button at the bottom.

The issue is not related to that but to Blender hanging on startup. To do some troubleshooting:

  • Ensure both your OS and drivers are fully up-to-date (and use official GPU drivers, not those provided by windows or tablet/laptop maker).
  • Try to disable any running antivirus.
  • Ensure you have no python executable available in your %path% envvar.
  • Try to re-download and re-install Blender.
  • Try the latest build from our buildbot.
  • Try to start Blender in factory settings (--factory-startup commandline option) (this will ensure whether this is a userpref or addon issue or not).
  • Try to tweak your GPU driver settings (e.g. try different values between 'performance' and 'quality' if you have such slider, etc.).
  • Launch Blender from the command line with -d option and attach as text file here any error printed out in the console (do not paste it directly in comment).
  • Try to run Blender through Software OpenGL, this will be much slower however, if everything works then it means that the bug is spefic for your GPU/Driver and you should report the bug to your GPU vendor instead.
  • On Linux/macOS, Official releases come with blender-softwaregl
  • On MS-Windows: Download this dll and copying it so its located in the same directory as 'blender.exe' and run Blender normally.

In addition to the troubleshooting steps mentioned by @Vuk Gardašević (lijenstina), have you tried posting/searching on any forums (e.g. StackExchange - https://blender.stackexchange.com/) to see if any of the tips mentioned there help?
